Add another skill unlock for trait research.

Incoming "carebear" request. There, i gave you a disclaimer.

Since trait research is locked at 3 pieces max at any one time, and the research times, even at rank 4 take at least several days at the fifth trait, could a 5th rank of Stitching/Metallurgy ect be added in the future that either further reduces the times or adds a fourth research slot? I'm really itching to get my end-game gear going...
